No access to account balance

My nedbank card on my husbands account was swollowed by nedbank ATM a few months ago. My card was replaced but we could no longer use IB. We have no was of seeing the account balance as it does not reflect on card at ATM, ussd and IB doesn't work anymore. We have raised this numerous times - nothing happens. We need to continually contact customer service to get a balance. We have this week logged 4 requests since Monday via customer service and still no response. This is unacceptable.
